Is a slider hitch worth the extra money?

I have the Pullrite Superglide and yes it does cost a little bit more but there has been several occasions that it surely saved my back window. You can always say just be careful when making a corner if you don't have a slider but it is the situations that you make quick decision that is going to be the trouble. I missed a corner once and decided at the last minute to turn around in a small parking lot and if I had not had my Superglide which is an automatic slider I would have definitely knocked my back window out. The cost for 1 rear window repair would justify the additional expense up front.
The excellent part of the Pullrite Superglide is it is TOTALLY AUTOMATIC you don't have to do anything.
